Your layout is pretty good for the amount of space you're working with.Here are some pictures. You can see the additional feed stations- one for calcium, one for grit and the rest are for feed.
I was thinking I would actually start separating her when I first feed to let everyone else feed and then bring her back after 10 min or so.
Might not hurt to try that idea of separating them during the initial morning feeding. I happen to have a run that's split in the middle, with a gate, so if a bird/some birds are guarding or chasing others too much around the feed bowls, I put them on side of the run and shut the gate, do my morning chores in there, and then open the gate back up when I leave.
 
	 
 
		 
			
		
		
		
	
	
			
		 
			
		
		
		
	
	
			
		 
			
		
		
		
	
	
			
		 
 
		 
 
		 
 
		 The small black container on the fencing is used for their fermented feed or mash. I will say that only 1 other chicken gets to eat with the queen "B" my brahma, but when she's done the others get their mash too. I'd try making a few minor changes and if that doesn't work I'd lock the bully up for a few days in a dog crate in the run and see if that changes her tune.
